Member Data Documentation
◆ mRxDuplicated
| uint32_t otMacCounters::mRxDuplicated |
The total number of frames dropped due to duplication, that is when the frame has been already received.
This counter may be incremented, for example when ACK frame generated by the receiver hasn't reached transmitter node which performed retransmission.
◆ mRxErrSec
| uint32_t otMacCounters::mRxErrSec |
The total number of frames dropped due to security error.
This counter may be incremented, for example when lower than expected Frame Counter is used to encrypt the frame.
◆ mRxTotal
| uint32_t otMacCounters::mRxTotal |
The total number of received frames.
This counter counts all frames reported by the platform's radio driver, including frames that were dropped, for example because of an FCS error.
◆ mTxErrCca
| uint32_t otMacCounters::mTxErrCca |
The total number of CCA failures.
The meaning of this counter can be different and it depends on the platform's radio driver capabilities.
If OT_RADIO_CAPS_CSMA_BACKOFF is enabled, this counter represents the total number of full CSMA/CA failed attempts and it is incremented by one also for each retransmission (in case of a CSMA/CA fail).
If OT_RADIO_CAPS_TRANSMIT_RETRIES is enabled, this counter represents the total number of full CSMA/CA failed attempts and it is incremented by one for each individual data frame request (regardless of the amount of retransmissions).
◆ mTxOther
| uint32_t otMacCounters::mTxOther |
The total number of unique other MAC frame transmission requests.
This counter is currently unused.
◆ mTxRetry
| uint32_t otMacCounters::mTxRetry |
The total number of MAC retransmission attempts.
Note that this counter is incremented by one for each retransmission attempt that may be triggered by lack of acknowledgement, CSMA/CA failure, or other type of transmission error. The
mTxRetry
counter is incremented both for unicast and broadcast MAC frames.
Modify the following configuration parameters to control the amount of retransmissions in the system:
- OPENTHREAD_CONFIG_MAC_DEFAULT_MAX_FRAME_RETRIES_DIRECT
- OPENTHREAD_CONFIG_MAC_DEFAULT_MAX_FRAME_RETRIES_INDIRECT
- OPENTHREAD_CONFIG_MAC_TX_NUM_BCAST
- OPENTHREAD_CONFIG_MAC_MAX_CSMA_BACKOFFS_DIRECT
- OPENTHREAD_CONFIG_MAC_MAX_CSMA_BACKOFFS_INDIRECT
Currently, this counter is invalid if the platform's radio driver capability includes OT_RADIO_CAPS_TRANSMIT_RETRIES .
◆ mTxTotal
| uint32_t otMacCounters::mTxTotal |
The total number of unique MAC frame transmission requests.
Note that this counter is incremented for each MAC transmission request only by one, regardless of the amount of CCA failures, CSMA-CA attempts, or retransmissions.
This increment rule applies to the following counters:
-
mTxUnicast -
mTxBroadcast -
mTxAckRequested -
mTxNoAckRequested -
mTxData -
mTxDataPoll -
mTxBeacon -
mTxBeaconRequest -
mTxOther -
mTxErrAbort -
mTxErrBusyChannel
The following equations are valid:
-
mTxTotal=mTxUnicast+mTxBroadcast -
mTxTotal=mTxAckRequested+mTxNoAckRequested -
mTxTotal=mTxData+mTxDataPoll+mTxBeacon+mTxBeaconRequest+mTxOther
